It turns out that Feeding Frenzy is a Shannox drop, while Avool’s is a shared drop from any of the bosses in Firelands.

So now I have two nearly identical slow daggers. I’ll end up dropping a few thousand gold on a Landslide enchant for my Shanker and reforging my gear to squeeze out maybe a 20 dps theoretical improvement (essentially no change). Maybe I’ll find a place where weapon-swapping is useful again.

I could complain about poor loot distribution by the designers, but it just happens that my guild has only one raiding rogue so I ended up with both daggers. Its weird to gripe about getting raid loot. I got two drops in two weeks, but it feels like the loot gods are taunting me.
